Recently, the team of Professor Li Chunzhong and Associate Professor Li Yuhang of East China University of Science and Technology proposed a series reaction strategy. Through hydrolysis and electrolysis, ADN and adipic acid (AC) can be extracted from waste PA-66 under mild conditions. ) and hydrogen (H2). The core-shell structure anode catalyst Ni3S2@Fe2O3 is designed with Fe2O3 nanosheets on Ni2S3 nanowalls to dehydrogenate C-N bonds into C≡N bonds. In the 100-hour stability test, the Ni3S2@Fe2O3 electrode
mA cm-2 current density (1.40 V vs.
The Faradaic efficiency of ADN produced under RHE is >85%. At the same time, hydrogen gas is produced at the cathode. The unique core-shell structure of Ni3S2@Fe2O3 enhances its electrochemical performance. X-ray photoelectron spectroscopy (XPS) also shows that the formed Ni(Fe) oxygen (hydroxide) species may be the real active species for C-N bond dehydrogenation. This strategy provides new ideas for the sustainable production of high-value commodity chemicals and clean H2 fuel from PA-66 waste.
